The flexibility and ubiquity of wireless communication solutions has played an important role in the explosive growth in mobile radios used in laptops, smartphones and tablets. With the evolution towards wearable and cyber physical systems, mobile systems promise unprecedented opportunities for monitoring and controlling personal health, cities and the environment. Today, we notice that this promise is only partially fulfilled, and important spectrum, battery and flexibility bottlenecks hamper the full potential of the next generation wirelessly connected systems. As 5G research is starting, various innovative ideas are being proposed to promise the much desired power and spectrum-efficient systems. In this talk, an overview will be given of possible 5G directions, from PHY to MAC and cloud, and how they link with a flexible 5G testbed.
